[c-nsp] ASA5520/ casas 7.0(4) meaning of MM_WAIT_MSG3 ?!

[jcovini at free.fr]

What's the meaning of MM_WAIT_MSG3 ?

This tunnel is correctly defined as a l2l,

tunnel-group 1.2.3.4 type ipsec-l2l
tunnel-group 1.2.3.4 ipsec-attributes
 pre-shared-key *

however, there is a strange type in the isakmp sa status, instead of L2L I got
this :

LAN2LAN#sh crypto isakmp sa
6   IKE Peer: 1.2.3.4
    Type    : user            Role    : responder
    Rekey   : no              State   : MM_WAIT_MSG3

failed, no match!
Jan 31 2007 14:23:43: %ASA-4-713903: IP = 1.2.3.4, Error: Unable to remove
PeerTblEntry

wtf ?!
